How many kcal per gram do fats provide?

Fats are known to be a dense source of energy, providing a significant amount of calories per gram compared to carbohydrates and proteins. Each gram of fat yields approximately 9 kilocalories. This high energy output is one of the reasons fats are essential in the diet, as they supply energy needed for various bodily functions and activities. Additionally, fats play critical roles in hormone production, cellular structure, and the absorption of fat-soluble vitamins (A, D, E, and K). Understanding the caloric content of fats helps people make informed dietary choices, especially when managing energy intake for weight maintenance or weight loss.
